Abstract

Journalism, advocacy, and active litigation attach the words “delusion” and “psychosis” to named individuals on the basis of public information: news accounts, self-reports, and court filings. This commentary argues that the practice fails on the diagnostic manual’s own terms, and that the failure runs in one specific direction. DSM-5-TR defines a delusion by fixity: a fixed belief that is not amenable to change in light of conflicting evidence. Fixity is legible only in trajectory, in whether the belief held or released when contradiction arrived, and never in how extreme the belief sounded at its peak. An asymmetry follows. Affirming the diagnostic label from public information is unavailable in principle, because affirmation requires a longitudinal record of the belief surviving contradiction, a negative symptom picture that public accounts do not carry, and the clearing of exclusion screens that operate before fixity is even reached. Refuting the label as applied, by contrast, requires exactly one datum that public accounts and court filings routinely supply: the documented moment the belief released on contradiction. A record that contains that moment has falsified the vocabulary it uses, in the same document, with no outside evidence required. The commentary derives a verdict rule, refutation without diagnosis: the careful observer may describe what the record shows, may classify the pattern it displays, and may demonstrate what the record rules out, while asserting nothing about what any individual has. It closes with the cost of the borrowed word: a definitional expansion that pathologizes people whose injury was deceptive design, and that dilutes the diagnosis for the community living with diagnosed psychotic conditions.
